PETER C. SMITH, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR-TO HIMSELF, EZRA S.

DOD GE,'AND LOUIS A. KOTZOW, OF THE SAME PLAGE.

The Schedule referred to n'these Letters Patent and making part of the Bama- To all whom fit may conce-Mt Beit known that I, PETER C. SMITH, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Safety-Toggle for Vest- Chains and other similar purposes.

To enable persons skilled in the art to make and use my invention, I do hereby declare that the following specification, taken in connectien with theI drawings furnished and forming a part of the same, is-a true and clear description thereof. 1

Figure 1 represents one of my toggles in perspective, with portion of watch-chain attached.

A represents a face-plate, more or less ornamnted', and of any desired form, furnished with a hook, or ring, to which the chain is permanently attached.

B B are dat standards, soldered to the bac-k of the tace-plate, connecting it with the barof the toggle by means of the barrel.

G is they barrel within which the bar proper operates.

D is a sliding bolt, or bar proper, near one end of which is a shoulder bearing against one end of the barrel C. The other end is of the same size as the interior of the barrel. A portion of the middle4 of the bar D is lunch smaller than at either end, around which is coiled a spiral spring, so set as to bear against a shoulder within the barrel C, and by pressure against a corresponding shoulder on the bar, forces it out, so that each end of.the bar projects equally from the barrel.

Figure 2 represents, in section, one of my toggles, showing the interior of the barrel O, and the spiral spring, before referred to.

The operation of the toggle is as follows:

By pressing upon the proper end of the bar D, it is forced through the barrel G, and while in that position, is readily inserted into the button-hole of a vest or other suitable aperture; Upon being vreleased from pressure, the bai-.springs out, and the toggle is securely attached to the vest, requiring the same particular manipulation to release it that was requisite for its inser tion.

I am well aware that shirt-studs, and perhaps sleevebuttons, havev been made before, possessingl a barrel, or

round standard, a bar, and a spiral spring, operating in a similar manner' to the bar of my toggle. Such fast# enings have a great value, but have hitherto been adapted only to eyelet-h'oles, and would not serve for use with the ordinary button-hole.

I wish it distinctly understood, therefore, that I make no claim to the use of the bar, the barrel, and the spring, in the formation of a safety-fastening.

My invention relates to a distinctive feature, novel to the trade, in the manufacture of watch-chains, resulting in a new article in the line of toggles, hitherto made of a straight bar, of a single piece of metal, inserted by the end,with a portion ofthe chain, through the button-hole, and then adj usted by the withdrawal of the chain.

The double standards B occupy an important posi-- tion as points in my invention, as, by their construction and position, the toggle is kept (while being worn) rmly in the button-hole, and does not sag down, or

.wear the hole by motion, as in the case of the ordinary toggle. These standards can be formed in one piece,

suliiciently broad to answer the purpose, although I prefer the double, as being lighter and neater.

Having thus described my invention,

I claim as new, and desire to secure by Letters
